Mineral fuel is the primary energy source in the world today, thereinto coal resource holds in store more than 75 percent in the total energy source. During coal's utilized, nocuousness matter expels into environment through all kings of method and works serious environmental pollution. Desulphurization has become one of primary objects of cleaning coal. At present, there are some primary problems of removing sulfur from coal. It is the size of coal is too small, the time of removing sulfur is too long, the technology is too complicated and the investment is much expensive etal.

中文题名燃煤微生物预处理浮选脱硫的试验研究副题名外文题名 Study on microbial pretreatment and floatation desulphurization in coal 论文作者周志付导师王英敏魏德洲教授学科专业安全技术及工程研究领域\研究方向学位级别博士学位授予单位东北大学学位授予日期2002 论文页码总数99页关键词燃煤微生物预处理－浮选脱硫煤炭脱硫馆藏号BSLW /2003 /X701 /2 矿物燃料是当今世界的主要能源，其中煤炭资源蕴藏量占总能源的75％以上，在煤的利用过程中，有害物质以各种方式排入周围环境，造成了严重的环境污染，因此脱硫已成为洁净煤技术的主要目标之一，而目前煤中硫的脱除存在的主要问题是：煤粉太细，脱硫时间长、技术复杂，投入费用太高等。

A new desulfurization apprach for pulverized coal combustion is introduced in this paper; pulverized coal is first burn in a precombustion furnace under oxygen deficient condition (about 30% air needed in boiler is provided for precombustion), in precombustion moust of sulfur in coal is decomposed and oxidized, and evolved, the sulfur evolved is trapped in a desulfurizing fluidized bed by calsuim, and then the char and gas are introduced to the boiler furnace for complete combustion.

本文提出了一种煤粉燃烧脱硫新方案，利用煤中硫优先氧化分解释出的原理，用少量的空气（大略为锅炉实际空气用量的30％），在一前置燃烧室中，使煤粉中硫的绝大部分被分解氧化，释放出来，释放出来的硫在脱硫流化床中被石灰脱硫剂脱除，未燃烧的炭粒与烟气再吹进锅炉膛中完全燃烧。

In addition, the proportion of pyritic sulfur in the total sulfur is increasing with the sizes.

The study of the forming condition and mechanism of immature oil in eastern Linqing depression reveals that brackish water-brine, abundant sulfur bacteria and sulfocompounds provided favorable conch-lions for the formation of the immature oil. Immature oil was the result of hydrogen-rich sapropel of lower activation energy degraded by sulfur bacteria. T and R of the early hydrocarbon generation of organic matter were 400~435℃ and 0.2%~0.5% respectively, and their values for peak hydrocarbon generaion are 420℃ and 0.35%.
